e18627 Background: An estimated 94,000 women have newly diagnosed gynecologic cancer annually–with rates increasing over the last 20 years. The incidence of gynecologic cancers is known to vary by insurance status; more specifically, uninsured or federally insured women are more likely to have advanced-stage disease at the time of diagnosis and worse overall survival compared to privately insured women. Surgical site infections (SSIs) complicate up to 4% of hysterectomies in the United States. Other post-operative sequelae, such as wound dehiscence and 30-day readmission, further complicate the post-surgical course. We sought to determine differences in postoperative outcomes for patients with private and federally-funded insurance plans, such as SSI, length of hospital stay, and 30-day wound dehiscence, and 30 all-cause readmission following gynecologic oncologic surgery. Methods: We conducted a retrospective cohort study from a large metropolitan academic health system between January 1st, 2022, to June 30th, 2022. The study population included adult women who received gynecologic oncologic surgery–surgical staging or interval cytoreduction. Postoperative complications were compared to national rates from the National Surgical Quality Improvement Project (NSQIP) database. Trends were analyzed using chi-squared analysis and a two-sample t-test. Results: Over our 6-month study period, 233 patients underwent gynecologic oncologic surgery. Robotic-assisted hysterectomies were the most common (27.89%, n = 65), followed by total abdominal hysterectomies (21%, n = 49), laparoscopic hysterectomies (7.72%, n = 18), and supracervical hysterectomies (3%, n = 7). More patients required bilateral salpingo-oophorectomy (63.51%, n = 148) compared to unilateral procedures (9.87%, n = 23). Although most patients had private insurance (73.39%, n = 171), 26.1% had federally-funded health plans (n = 62)–Medicaid and Medicare. Rates of wound dehiscence were higher than the NSQIP rate of 1% among our cohort (3%, n = 7). Although there was a high rate of 30-day readmission (9.44%, n = 22) compared to NSQIP rate of 6.1%, the incidence of SSI was fewer than the NSQIP rate of 4% (3.86%, n = 9). Upon intersectional analysis, patients with federal insurance plans had higher rates of SSI (n = 5, p &lt; 0.05). Specifically, Medicare patients had a longer average length of stay at 2.64 days (p &lt; 0.05) compared to a study average of 1.76 days. Conclusions: Patients with federal insurance had longer hospital stays and higher rates of SSI compared to those with private plans. There was no difference in 30-day wound dehiscence or 30-day all-cause readmission between study populations. More studies are needed to risk-stratify patients by insurance type before gynecologic oncology surgery to improve postoperative outcomes further.
